Description of key information

No acute toxicity study with zinc dipropionate is available, thus the acute toxicity will be addressed with existing data on its two individual moieties zinc and propionate, respectively propionic acid.

Based on in vivo acute toxicity data on the moieties, it can safely be assumed, that zinc dipropionate has no pronounced acute toxicity.

Please refer to the section for the respective assessment entity for data on the moieties.

Key value for chemical safety assessment

Acute toxicity: via oral route

Endpoint conclusion
Endpoint conclusion:
no adverse effect observed

Acute toxicity: via inhalation route

Endpoint conclusion
Endpoint conclusion:
no adverse effect observed

Acute toxicity: via dermal route

Endpoint conclusion
Endpoint conclusion:
no adverse effect observed

Additional information

An acute toxicity leading to clasification is not expected for zinc dipropionate, since the two moieties zinc and propionate, respectively propionic acid are not classified for acute toxicity. Under the assumption that the moieties of zinc dipropionate show their toxicological profile individually upon dissolution, acute toxicity estimates (ATE) for the acute oral and inhalative (systemic) toxicity of zinc dipropionate can be calculated using the equation given in regulation (EC) 1272/2008, Annex I, Section 3.1.3.6.1.

Because of lacking of a dose descriptor for the acute dermal toxicity of the zinc moiety, an acute toxicity estimates (ATE) for the acute dermal (systemic) toxicity of zinc dipropionate can not be calculated. However, the dose descriptors for the acute toxicity of the moieties via the oral route are very high (substantially > 2000 mg/kg bw). Thus, it can safely be assumed, that zinc dipropionate has no pronounced acute dermal toxicity.

There are no indications on narcotic effects.

For further information on the toxicity of the individual moieties, please refer to the relevant sections in the IUCLID and CSR.

Justification for classification or non-classification

Based on in vivo acute toxicity data on the moieties, it can safely be assumed, that zinc dipropionate has no pronounced acute toxicity. There are no indications on narcotic effects.

According to the criteria of REGULATION (EC) No 1272/2008 and its subsequent adaptions, Zinc dipropionate does neither have to be classified and has neither obligatory labelling requirement for acute oral, inhalative or dermal toxicity nor for specific target organ toxicity after single exposure (STOT SE narcotic effects).
